Petzval Lens STOP Analysis with Surface-to-Surface Radiation
Application ID: 63831
This model demonstrates an integrated structural-thermal-optical performance (STOP) analysis of an optical system. The Petzval Lens tutoral is used as the basis for this model, together with a simple barrel geometry
The isothermal model performs a Parametric Sweep over several uniform temperature values and the effect on the displacement fields and image quality as a function of temperature is shown.
The other (non-isothermal) includes a thermo-vacuum enclosure where the exterior temperature is significantly different from the interior. The lens assembly is placed inside this enclosure and is exposed to this exterior via a pair of windows. The resulting temperature gradients and displacement fields within the optical system are shown as well as with the effect on image quality.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
- COMSOL Multiphysics® and
- Ray Optics Module and
- either the MEMS Module, Metal Processing Module, or Structural Mechanics Module and
- either the Acoustics Module, MEMS Module, Multibody Dynamics Module, or Structural Mechanics Module
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
